Warm yet Punchy Mic Pre

If you are looking for big punch and fat tone from a 500 series preamp, look no further. The Burl B1D has huge tone, from heavy and gainy to clean and warm. Get rid of all that extra EQ and compression and replace it with real preamp warmth. The B1D has an iron transformer giving it a bigger rock tone than its nickel transformer eqipped brother, the B1. Extensively tested with many mics, including ribbon mics, this mic pre continually offers up great tone. The Class-A audiophile circuit and custom BX4 output transformer combine to deliver amazing punch on drums and warmth on vocals. If you are looking for a new 500 series preamp be sure to checkout the Burl B1D.

Buy This Pre

I have used multiple 500 series units and have other top notch press, This thing really has one of the warmest sounds I have ever heard especially on guits and bass. It is also fantastic on vocals (especially if you add a little compression).Could not be happier with this purchase!!!

Our secret weapon

This has been my little secret for awhile now but others need to know: this Pre sounds phenomenal! We tested it thoroughly against the API 512c and UA 610 and, though they both sound great, there was a clarity and vibe to the Burl tracks that brought our tracks to the next level. If you haven't converted to Burl, don't hesitate!

Sweetwater Advice

Thomas Leahy

When I need to add depth and warmth to an overly clean source, I can count on my Burl B1D. It's an amazing bass DI/preamp, and when I drive this transformer-based preamp into its sweet spot, it sounds like an old console pushed to its limits. Paired with a ribbon mic, the B1D works great for amps, and I get huge 3-dimensional guitar tones when use it alongside neve-style preamps.
